| - | Shells: |
| - | |
| - | lash is the very smallest shell (adds just 10k) and it is quite usable as |
| - | a command prompt, but it is not suitable for any but the most trivial |
| - | scripting (such as an initrd that calls insmod a few times) since it does |
| - | not understand Bourne shell grammer. It does handle pipes, redirects, and |
| - | job control though. Adding in command editing makes it a very nice |
| - | lightweight command prompt. |
| - | |
| - | hush is also quite small (just 18k) and it has very complete Bourne shell |
| - | grammer. It handles if/then/else/fi just fine, but doesn't handle loops |
| - | like for/do/done or case/esac and such. It also currently has a problem |
| - | with job control. Using hush is not yet recommended. |
| - | |
| - | msh: The minix shell (adds just 30k) is quite complete and handles things |
| - | like for/do/done, case/esac and all the things you expect a Bourne shell to |
| - | do. It is not always pedantically correct about Bourne shell grammer (try |
| - | running the shell testscript "tests/sh.testcases" on it and compare vs bash) |
| - | but for most things it works quite well. It also uses only vfork, so it can |
| - | be used on uClinux systems. This was only recently added, so there is still |
| - | room to shrink it further... |
| - | |
| - | ash: This adds about 60k in the default configuration and is the most |
| - | complete and most pedantically correct shell included with busybox. This |
| - | shell was also recently added, and several people (mainly Vladimir and Erik) |
| - | have been working on it. There are a number of configurable things at the |
| - | top of ash.c as well, so check those out if you want to tweak things. |
